Martin Ernst Heckmann, Marco Moebus, Frank Joublin, Christian Goerick , "Speaker Independent Voiced-Unvoiced Detection Evaluated in Different Speaking Styles", Proceedings of Interspeech, pp. 1670-1673, 2006.
AbstractWe propose a new algorithm for voiced/unvoiced classification of speech on a phoneme or sample level. The algorithm is inspired by auditory based approaches and combines two cues. One cue is based on the energy distribution of the signal and the other on the harmonicity. In order to extract the harmonicity of the signal we calculate a histogram of the zero crossings of the filter channels after applying a Gammatone filterbank to the signal. A mea...

Thomas Bihrer , "Direct Manipulation of Free-Form Deformation in Evolutionary Optimisation", TU-Darmstadt, 2006.
AbstractThe choice of an adequate representation is an important part of every evolutionary design optimisation. A exible representation which allows a huge number of design variation while getting along with a few parameters is preferable. In the past the Free-From Deformation method was successfully applied for design optimisation. In this diploma thesis an adaptive Free-Form Deformation is combined with an Evolution Strategy. The aim is to automatica...

AbstractMost algorithms based on Computational Auditory Scene Analysis (CASA) for binaural speech separation do not have the ability to inhibit already localized and for a long time present sources in the auditory scene. This has the major drawback that the auditory cues of weaker and new sources are subject to interference from already localized and perceived signals and the separation performance is worse if the signals overlap in their processing doma...

Volker Willert , "Rekurrente visuelle Bewegungssegmentierung", Technische Universität Darmstadt, Fachgebiet für Regelungstheorie und Robotik, 2006.
AbstractIn dieser Arbeit wird ein biologisch motiviertes Verfahren zur Bewegungsschätzung in Videosequenzen vorgestellt, welches das Korrespondenzproblem auch in störbehafteten Videoaufnahmen bei Farbrauschen und Beleuchtungsänderungen lösen kann und damit eine robuste Schätzung des optischen Flusses in realen Bildaufnahmesituationen liefert. Dazu wird ein stochastisches Modell zur Messung von Geschwindigkeiten entwickelt, das unterschiedliche Mehrdeutig...

Michael Gienger, Herbert Janßen, Christian Goerick , "Exploiting Task Intervals for Whole Body Robot Control", Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006.
AbstractThis paper presents a whole body motion algorithm and shows some steps towards its feasibility in complex scenarios. We employ the framework of Liegeois which solves the redundant inverse kinematics problem on velocity level. To make the controller suitable for a variety of different applications, task descriptors for the relative effector positions as well as a one and two-dimensional attitude representation are proposed. The inverse kinematics ...
